*****Skyote #88 gets Bronze Lindy for "Airventure-Oshkosh 2016 Plans Built Champion"******

October, 2007

Welcome to "Skyotelog", the build record of Skyote #88. I assume that you are familar with the Skyote biplane. If not, you should visit http://www.skyote.org/ for a complete introduction to this unique but elusive biplane.

The posts are presented in reverse chronological order (newest first). Or you can click on one of the "Labels" to see all of the posts concerning a specific topic. Click on any photo for a larger image.

All my building experience is limited to Van's RV's so I have no experience with building tube and fabric or "plans building". I have much to learn so take everything I write with a grain of salt and reasonable skepticisim.

I do not intend to follow a "traditional" path for the construction of #88. I intend to employ low level technology and $ to reduce the construction time and difficulty where possible and practical. By low level technology I am referring to CAD, laser, waterjet, CNC. For example:

  • I have purchased a complete wing spar kit from Jerry Kerr.
  • A rib kit from Mr. Bartoe.
  • Brunton Flying Wires and Drag wires from Harvey Swack.
  • CNC profiled tube kits for the fuselage, tail feathers and landing gear from VR3.

In addition I have converted all of the wing fittings, brackets, links, lugs etc. to CAD and had them cut by water jet. I have designed a laser cut wing spar drill template/jig which positions the five spar components so that all of the holes can be drilled in a complete spar as an assembly. I plan to continue converting as many parts as I can to CAD so that I can reduce the "hand-made" components to a minimum.

Note: As of June 2015 I have over 100 CAD files which provide 600+ water jet cut parts for the Skyote.

While it takes a little time, converting the design to CAD is a great way to truly understand the drawings. plus a huge amount of information has been extracted from the rather complex drawings. This can be a great help to others in understanding and interpreting the design.

The Skyote is uniquely suited for conversion to CAD in that a "computer" was used in it's original design. I have read that Mr. Bartoe used a HP calculator to "compute" the design and dimensions of the Skyote. The plans show all of the critical dimensions to three decimal places for X,Y and Z axes.

Amazingly, when I put the design into CAD the resulting 3D models agree with Mr. Bartoe's thee decimal place dimensions about 99.9% of the time. I have found one discrepancy but less than 0.030"!

If you want to build your Skyote as cheaply as possible, or if you enjoy handcrafting the same parts over and over again then my approach to building is not for you!

If you want to build your Skyote in the minimum possible time with highly accurate parts then this approach may be the answer. I personally get a lot of satisfaction out of organizing the project so that it can be produced accurately. Hopefully some of this work will prove useful to others in the future.

Skyote #88 Flies

Skyote #88 flew for the first time today. It was flown by long-time friend, Bob Cabaniss.
It got off quick, flew straight and landed nicely!  A Good Day".

The following is a so-so YouTube video of the first departure and return to the hangar.  More later.

The Big Day!!

It's an Airplane!

Skyote #88 passed its inspection today and received its Airworthiness Certificate. FAA representatives Paul Fodor, center, and James Dangerfield, right, gave her the once over (three times) and pronounced her ready to fly. They did a great job and turned up a number of  things which needed remedial action. Fortunately, they were all minor and were corrected on the spot while the inspection was in progress. Scheduling conflicts, dental appointments, and weather will delay the first flight for a few days but it won't be long now!

Yours truly with Pink Slip in hand!
I was hoping my shirt would not be a bad omen!

Of course the Peanut Gallery was there to offer encouragement.

All great friends but special thanks to Tom and Les. I wouldn't have made it with out them!
Also very special thanks to Dale Doane, not pictured, for his outstanding contributions in tig welding and beautiful metal fab work. His outstanding work inspired us all to try to do the best we could. Also to Johnathan Pritchard for the patience and skill necessary to produce the hundreds of water jet cut fittings and components necessary for the completion of the Skyote.
